The Golden Proportion

The Golden Proportion is an ancient phenomenon unlocking an unparalleled understanding of beauty in nature, art, and science, known about since the time of the Ancient Greeks. The Golden Proportion is your first step toward an eye-opening adventure that will enrich your life with a new understanding. It will take you on a journey of discovery into an unexpected dimension of beauty affecting our lives at every turn.

The major landmarks of the beauty of nature all seem to be related together through the Golden Proportion. Notice how many places the Golden Proportion can be found in one small moth. Even if one item is a fraction out of place, it would upset the Golden Balance of all of them – and beauty would be lost.

The Golden Mean Gauge

Using the Golden Proportion Gauge will enable you to enrich your life with a new understanding of beauty in nature, art and science. The Golden Proportion has been known about since the time of the ancient Greeks who used it in their works of art.

The Golden Proportion Gauge can be used for your own art and design, allowing you to be confident of success.  The original gauge made by Dr Levin is laser cut from stainless steel to provide accuracy in measuring very small to larger items. Expect it to last a life time. Other gauges are made from clear Perspex, and a larger Perspex gauge is suitable for larger artistic projects such as sculpture.

The gauges make perfect gifts for anyone interested in the beauty of nature, art and science.

Concepts

The concept of the Golden Proportion is easy to understand but it's very simplicity has been perplexing and so this enchanting proportion has not been appreciated at large. Hard to believe that such a simple concept can be at the core of so much confused discussion about proportion.

Proportion usually implies a relationship between a larger and a smaller. To clarify the Golden Proportion concept, the adjacent figure shows a number of pairs of lines of different lengths and their ratio to each other. The last line shows the ratio of 1 to 0.618, which is the simplest form of the Golden Proportion.

Dr Eddy Levin

As a young dentist, Eddy Levin wondered why carefully made teeth still looked false. Studying the golden proportion at the same time, he saw the link, and crowned a hospital patient’s front teeth by it. The gauge grew from that case.
